• C. The virtual machine does not occupy memory when it is turned off
• D. The memory allocated to a virtual machine can be greater than the physical memory

Which of the following statements about sharing files is correct?

• B. After the installation is complete, you need to confirm the image file selection in the virtual drivers menu. The ISO file has been disconnected.

The following statements about x86 architecture virtualization are correct:

• A. In the paravirtualization solution, the hypervisor provides a hypercall interface to meet the key kernel operations of the guest OS, such as memory management, interrupt time synchronization, etc.
• B. Hardware-assisted virtualization solution introduces VMCS (virtual-machine control structure), which stores the relevant status information of the virtual CPU
• C. The original x86 architecture was not suitable for virtualization because sensitive non-privileged instructions could not be captured by the VMM
• D. Full virtualization solution requires modification of guest OS

Set the virtual machine startup priority. Which of the following statements is correct?

• A. If the virtual machine startup priority is set to default, the startup priority set in the cluster will be used.
• B. The virtual machine startup priority can be set to: default, low, medium, high
• C. The virtual machine startup priority can be configured on the virtual machine or on the cluster
• D. If both the virtual machine and the cluster set the startup priority (the virtual machine is set to non-default), the startup priority set in the cluster will take precedence.
